/**
 * RestController注解:
 *   1.组合注解,等价于: Controller + ResponseBody;
 *   2.使用该注解后,控制器方法上就不需要再添加 ResponseBody 注解了;
 *
 * Slf4j注解:
 *   1.Lombok中的日志注解,添加在类上,会自动生成日志对象log;
 *   2.使用日志对象log,记录日志信息,比如:
 *     log.trace("日志信息");
 *     log.debug("日志信息");
 *     log.info("日志信息");
 *     log.warn("日志信息");
 *     log.error("日志信息");
 *
 * Knife4j注解:
 *   1.@Tag(name=""):调整控制器类名在Knife4j文档中的显示名称;
 *   2.@Operation(summary = ""):调整控制器方法名在Knife4j文档中的显示名称;
 *   3.@ApiOperationSupport(order = 10):调整控制器方法排序,数字越小,优先级越高;
 *   4.@Schema(description="",required=true,example=""):DTO类属性描述;
 *   5.@Parameter(name="",description="",required=true,example=""):非封装参数[单个]描述;
 *   6.@Parameters(value = {@Parameter(),@Parameter()}):非封装参数[多个]描述;
 *   7.隐藏指定的参数:@Parameter(name="",description="",required=true,hidden=true);
